• The C–H activated controlled mono- and di-olefination of arenes in ionic liquids at room temperature
  作者：Kaifeng Du、Tian Yao

  DOI：10.1039/c9ra09736h

  日期：——

  In this study, controlled mono and di-olefination of arenes was first realized at room temperature via the C–H bond activation in ionic liquids, probably due to the positive effects of ionic liquids. It is an energy-saving routes in industrial production without the need for heating equipment. Different catalysts were screened, and it was found that [Ru(p-cymene)Cl2]2 generated mono-olefinated products

  在这项研究中，芳烃的受控单烯和双烯化首先在室温下通过离子液体中的C-H键活化实现，这可能是由于离子液体的积极作用。它是工业生产中无需加热设备的一条节能路线。筛选了不同的催化剂，发现[Ru( p-伞花烃)Cl 2 ] 2主要生成单烯化产物，而[Cp*RhCl 2 ] 2选择性生成二烯化产物。这些催化剂（[BMIM]NTf 2和[BMIM]PF 6）作为绿色且可回收的反应介质，在温和条件下具有高效性。该反应过程可以避免任何挥发性和对环境有毒的有机溶剂，并且不需要密闭设备，更加安全。实现了宽底物范围、良好的产率和令人满意的选择性。该反应可以放大至克级。此外，昂贵的铑/钌催化体系可循环使用至少6次，且始终保持较高的催化活性，从工业角度来看是经济且环保的。根据机理研究，C-H键断裂可能是通过协同金属化-去质子化来实现的。该技术可用于多种有价值的不饱和芳香族化合物的合成，显示出巨大的工业化生产潜力。

  What a couple! Arenes functionalized with donating groups undergo oxidative dehydrogenative coupling with alcohols in the presence of a copper/silver catalyst system. This intermolecular CH alkoxylation provides a convenient synthetic route to the important class of aryl ethers. The catalyst system also allows the alkoxylation of benzylic CH groups with formation of benzyl alkyl ethers.
